Nuclear Fuel Materials, Fission Product Behavior, and Actinide Superconductivity
This community investigates the physical and chemical properties of nuclear fuel materials, the behavior of fission products under reactor conditions, and the electronic structure of actinide compounds, including the superconducting properties of uranium-based metals.
The work centers on uranium dioxide, uranium nitride, and mixed oxide fuels, analyzing their thermal conductivity, crystal structure, and phase transitions. Researchers model fission gas release and severe accident scenarios using molecular dynamics and density functional theory. A significant portion of the literature addresses the structural and electronic properties of actinide compounds, with a distinct focus on the superconducting behavior of uranium ditelluride (UTe2). Methods include first-principles calculations, high-throughput determination of Hubbard U values, and experimental characterization of thin films and fuel pellets. The community also examines the incorporation of rare earth elements and fission products into ceramic matrices, such as zirconia, to understand material degradation and stability.
The largest share of the community's output is found in plutonium research, accounting for 9.0% of all plutonium research, and 3,290 papers here. Uranium research contributes 7.1% of its total output, with 7,833 papers in this group.
The community comprises 42,700 papers, published primarily in the Journal of Nuclear Materials, Physical Review B, and Journal of Magnetism and Magnetic Materials.
Recent work continues to focus on the superconducting surface states of UTe2 and the phase transformation mechanisms in uranium-molybdenum-titanium-zirconium alloys. New studies also examine defect-induced phonon scattering in irradiated thorium dioxide and the structural insights into americium incorporation into zirconia.
